Is a hydrogen atom bigger than an oxygen atom?
An oxygen atom is about 2% bigger than a hydrogen atom.
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
No the hydrogen and oxygen atoms do not equally share their electrons. The oxygen atom has a greater electronegativity than the hydrogen atom, which means that the oxygen atom has a greater attraction for electrons than the hydrogen atom.
The oxygen atom has a greater electronegativity than the hydrogen atom, which means that the oxygen atom has a greater attraction for electrons than the hydrogen atom. Because of this, the oxygen atom develops a slight negative charge and each hydrogen atom develops a slight positive charge.
A sulfur atom is larger than an oxygen atom.
First of all, there is no nitrogen in a water molecule. A water molecule consists of one oxygen atom combined with two hydrogen atoms. Also known as H2O. However, it is also true that an oxygen atom is slightly bigger than a nitrogen atom. Oxygen has one more proton, and one more electron than nitrogen does. Neutron quantities vary, since there is more than one isotope of both oxygen and nitrogen.
Oxygen has a stronger attraction for electrons because there is a greater probability of finding the shared electrons near the oxygen atom than near the hydrogen atom, due to the higher electronegativity of oxygen compared to hydrogen.
Explain why in a covalent bond between oxygen and hydrogen the hydrogen atom has a partial positive charge and the oxygen atom has a partial negative charge?
In covalent bonds, not all electrons are shared equally. Oxygen is more electronegative than Hydrogen, so it attracts the electrons closer to the Oxygen than the Hydrogen.
Hydrogen has a molecular mass of 1 where as an oxygen atom has a molecular mass of 16 so oxygen is heavier than hydrogen
In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.
No, it is inverse.
A hydrogen only has one valence electron, while oxygen has 6.
oxygen attracts electrons stronger than hydrogen
As hydrogen has more protons than electrons and oxygen has more electrons than protons. But it isn't that simple oxygen is in a group with negative charges and different groups have different charges. I'm not sure of hydrogen it is somehow different but haven't learnt that yet
cuz it just is :)
Electronegativity differences. There are more protons in an oxygen atom than in a hydrogen atom, so any electrons being shared between them (as in the covalent bond) are more likely to be near the oxygen atom than the hydrogen atoms. This results in a slight net negative charge surrounding the oxygen atom, and slight net positive charges surrounding the hydrogen atoms.
Because an alpha particle is bigger than a helium or hydrogen atom.
the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus.
A hydrogen atom has a diameter of about 60 picometers while a proton has a diameter of 1.75 femotometers. So a hydrogen atom's diameter is about 35,000 times that of a proton.
No, methanol is more polar due to high electronegativity of oxygen and attachments of a carbon and a hydrogen atom to the oxygen atom.
Oxygen attracts electrons more strongly than hydrogen does.
No. A third hydrogen atom can not join a water molecule. However, it can partially join a water molecule through a process called hydrogen bonding. So the third hydrogen is more attached to its own oxygen atom than it is attached to the other oxygen atom although it is attached to both.
The pressure in a gas cylinder containing hydrogen will leak more quikly than if it is containing oxygen?
No matter how tight a container is, it is limited to the molecular structure of the material it is constructed from. Hydrogen is the smallest atom on the periodic table. An Oxygen atom is considerably larger than a Hydrogen atom. The Hydrogen will actually leak from the container faster, due to its small size. It actually leaks into and through the material of the container.
A water molecule is made up of two atoms of hydrogen and one atom of oxygen. Oxygen atom has six electrons in its outer most shell and a hydrogen atom has one electron in its outer most shell. Oxygen and hydrogen atoms are unstable because they have less than eight electrons in their outer most shells. Oxygen needs two electrons and hydrogen atom requires one electron tocomplete their valence shell. Oxygen atom combines with two… Read More
Hydrogen has only one electron. It can form only one covalent bond with another atom. In the water molecule, two hydrogen atoms bond with an oxygen atom. The oxygen atom has two unpaired electrons and each hydrogen pairs its single electron with one of the unpaired electrons of the oxygen atom. So two separate H-O bonds form to produce a water molecule.
Positive. Since the Oxygen atom has a higher electronegativity (it is more likely to draw in electrons) than the Hydrogen atoms, the electrons that are shared in the two oxygen/hydrogen bonds will move closer to the Oxygen atom. This will give the Oxygen atom a slightly positive charge and the 2 Hydrogen atoms a slighty negative charge. Because of this, a water molecule is considered polar.
Water is H2O. Hydrogen peroxide is H2O2. Hydrogen peroxide has one more oxygen atom per molecule than water. The extra oxygen is what makes it a peroxide. "Hydrogen oxide" would be water. The extra oxygen also makes hydrogen peroxide much more reactive than water due to the unstable oxygen-oxygen bond.
Oxygen is more electronegative than hydrogen. Hence the shared electron pair is slightly towards oxygen (than hydrogen) giving it slightly negative (charge).
Water is H2O and hydrogen perioxide is H2O2 hydrogen peroxide has one more oxygen atom than water.
The hydrogen bonding effect is weaker between ethanol molecules than between water molecules. Both molecules have a "bent" structural pattern in the bonds formed with the oxygen, so we must consider the effects of the two surrounding groups. In water, the oxygen atom is surrounded by two hydrogen atoms, each donating equal amounts of electron density to the oxygen atom. In ethanol, the oxygen atom is surrounded by one hydrogen atom and one organic CH2CH3… Read More
helium as it contains 2 protons, while hydrogen only contains 1. Additionally, the orbit of the 2 electrons in a neutral helium atom would also be larger than the orbit of the single electron in hydrogen.
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
Due to the ability of the nucleus of oxygen atom to attract the electrons of the covalent bond to itself is higher than that of the nucleus of hydrogen atom, so oxygen atom carry partial negative charge and hydrogen carry partial positive charge
If you take a look at the Periodic Table of Elements, you'll notice that sulfur is directly underneath oxygen. According to trends in the Periodic Table, one knows that the size of the atom of sulfur is larger than that of oxygen because there are more electrons in a higher energy level surrounding the nucleus. The bond between both hydrogen and oxygen and hydrogen and sulfur are covalent. That means that the lone electron around… Read More
There is sixty percent water in your body. Water is made up of oxygen and hydrogen. There are double the number of hydrogen atoms or molecules as compared to oxygen in the water. But you have the mass of oxygen atom or molecule is 16 times more than that of hydrogen atom or the molecule. In case of water hydrogen to oxygen mass is one to eight, in proportion.
Because the oxygen atom is so much more electronegative than the hydrogen atoms, the electrons are not shared equally and are held more tightly by the oxygen atom, giving it a partial negative charge, and giving the hydrogen atoms a partial positive charge.
That depends on the atom. An atom of oxygen is 16 times heavier than a hydrogen atom (the lightest atom). Uranium atoms are over 200 times heavier than hydrogen. Regardless of what type of atom it is, a single atom won't weigh very much. well i assure you it is small and light specify the question more
H20 is a chemical formula. H stands for Hydrogen, O stands for Oxygen. An Oxygen atom has a different makeup than a Hydrogen atom. So H20 means there are 2 hydrogen atoms and 1 Oxygen atom. H20 is essentially H201, but the 1 is silent. Atoms make up everything.. Every substance.. etc. You'll learn about it in 8th grade.
the direction is towards the oxygen since the Oxygen atom has a much higher eletronegativity than either of the three Hydrogen atoms or the Carbon atom itself.
No, the opposite occurs. As the oxygen atom is much larger, it has a bigger 'pull' on the shared electrons, creating an uneven distribution of electrons known as a permanent dipole. No, Oxygen pulls the electrons more strongly than the Hydrogen, resulting in a partial negative charge on the Oxygen, and partial positive charges on the hydrogens.
A water molecule is made of two hydrogen atoms and one oxygen atom. The hydrogen atoms are smaller than the oxygen atom. They are bonded together by covalent bonds in a 'bent' shape (like a shallow 'v') with the oxygen in the middle, at the point. The 'v' shape is because the oxygen atom has two pairs of unbonded electrons on, and they push the bonds further round the atom.
Ethanol : C2H5-O-H Water : O-H-O One of the Oxygen atom in water can form a Hydrogen bond with the last Hydrogen atom as shown above. Hydrogen bonds are the electrostatic forces of attraction between an electron-deficient hydrogen bonded to a very electronegative atom and the lone pair of a neighbouring very electronegative atom. In Ethanol, the final Hydrogen is bonded with Oxygen, which is a very electronegative atom, therefore the Hydrogen atom is electron-deficient… Read More
water molecule is polar due to higher electronegativity of the oxygen atom than hydrogen. The oxygen molecule pulls the shared pair of electrons partially towards itself resulting in the hydrogen atom having a small positive charge on it and the oxygen atom having a small negative charge, thus causing polarity.
Basically this is because of unequal sharing of electrons. The oxygen atom is much more electronegative than the hydrogen, so the electrons tend toward the oxygen nucleus so that the oxygen atom is relatively negative and the hydrogen atoms are relatively positive. Also, the hydrogen atoms are not directly opposite each other across the oxygen atom - the angle between their bonds with the oxygen is 104.5 degrees. This causes a dipole moment, meaning that… Read More
An atom is a single atom of an element. For example an atom of Helium(He) A molecule is two or more atoms bonded together. So hydrogen in its natural state of H2 is a molecule containing two hydrogen atoms. Another example is H2O which contains to atoms of hydrogen and one atom of oxygen
Yes. Table sugar consists of an organic molecule known as sucrose. Sucrose contains many carbon and hydrogen atoms. Because of this, a molecule of sugar is much large than a molecule of water, which consists only of an oxygen atom bonded to two hydrogen atoms.
They are partial charges, making the water molecule polar. This occurs because the oxygen atom is more electronegative than the hydrogen atoms, and therefore holds the electrons more tightly than the hydrogen atoms. This gives the oxygen atom a partial negative charge and the hydrogen atoms a partial positive charge.
If you are mentioning about sticking two hydrogen atoms with one oxygen atom, then it's water. Other than that, oxygen and hydrogen are not together, unless they are water, hydrogen peroxide, or some other compound with an -OH group. In such compounds the hydrogen and oxygen are held together by covalent bonds, the sharing of electrons.
The innermost shell of any atom bigger than hydrogen (H) will contain 2 electrons.
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
2 hydrogen, 1 oxygen. The equation for water is H2O, meaning 2 parts hydrogen and 1 oxygen. Oxygen is a bigger element than hydrogen, hydrogen being the least dense substance on earth (which is why it rises in air) External links to a picture of a magnified water molecule:
